10 Claims.

The present invention relates to a novel window construction of the double-hung or slidable sash type and especially to a novel jamb construction and weathering means between the sliding sash and the surrounding window frame.

Among the objects of the present invention is the provisionof a novel weathering or sealing means for the side or vertical railsof the slidable sashes. This weathering is anchored to and carried by the side rails and has a wiping contact with a dovetailed sash-run jamb in a manner to effect optimum sealing with a minimum of frictional resistance to the raising and lowering of the sash.

The invention further comprehends novel remaximum simplicity, efficiency, economy and' ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

The invention further resides in the construction, combination and arrangement of parts illustrated in the accompanying drawings, and while there is shown therein a referred embodiment, it is to be understood that the same is'susceptible of modification and change, and comprehends other details, arrangements of parts. features and constructions without departingfrom the spirit of the invention.

In the drawings:

Figure 1 is a view in front elevation of the novel window construction.

Figure 2 is a fragmentary enlarged view in horizontal cross section through the window assembly.

Figure 3 is a' fragmentary enlarged view in vertical cross section through the window assembly.

Figure 4 is an enlarged fragmentary view in horizontal cross section through the dovetailed sash-run jamb and weathering.

Figure 7 is a perspective view of a novel mullio clip.

Figure 8 is a fragmentary view in vertical cross tional views similar to Figure 4 but showing alternate forms of weathering for the side rails and side jambs.

Referring more particularly to the drawings and the embodiment therein illustrated, the invention 'comprehends a novel metal window construction I shown in front elevation in-Figure 1.

This window assembly comprises a metal frame' 2 and slidable upper and lower sashes 3 and 4,

respectively. The frame is preferably of rolled construction, suitably joined at the corners as by welding or the like, and includes side jambs 5 reinforced by a vertically arranged strengthening member or channel 6 and suitably anchored in the window opening by means of anchoring plates 1. The side jambs are formed or provided with vertically extending dovetailed sash-runs 8 and 9 separated by a parting strip l0. These dovetailed sash-runs or channels are adapted to receive the spaced sides or projections of the side rails II and weathering l2 carried thereby. This weathering is shown more clearly in Figures 2 and 4 of the drawings, and comprises a sheet or strip of resilient metal extending for the length of the rail and formed into the shape of a substantially U-shaped member l3 into which a strip of cloth I4 is rolled with the opposite ends of the cloth anchored at l5 and Hi. This cloth may be of canvas duck and is preferably impregnated with paramn or other permanent lubricant. In order to properly anchor the weathering upon the side rails I l of the sash, the oppositesides l1, ll of the rails are each provided with an inwardly and rearwardly sloping flange or projection I8 against and behind which the ribs IQ of the member l3 seat.

The head jamb 20 is formed in a manner similar to that of the side lambs and is provided with spaced dovetailed grooves or channels 2| and 22, the former adapted to receive the upper or top sash rail 23 when the upper sash 3 is in closed position. In order to most effiectively seal and exterior surface thereof.

The bottom rail 21 of the lower sash 4 is provided with spaced projections 28 and 29 receiving and anchoring a resilient metal Weatherstrip 30 therebetween. This weathering is so formed as to provide projections 3| and 32 adapted to seat behind and interlock with inwardly projecting flanges 33 and 34 provided on the spaced projections 29 and 29, respectively; as more clearly shown in Figure 10. In order that these projections 29 and 29, along with the weatherstrip 30, form a weather-tight seal with the sill 35 when in closed position, this sill is provided with spaced steps 39 and 31 with the inwardly extending ends 39 and 39 of the weathering 30 contacting the step 33, and due to th resiliency of the Weatherstrip, the ends of the latter are moved or forced inwardly in the manner shown in Figure 3. When this Weatherstrip 30 is not in engagement with the sill, the ends 39 and 39 thereof contact or close in lapped relation 50 as to provide an uninterrupted exposed surface (see Figure 10) which will exclude dust and dirt and will render it less subject to damage in use.

As more clearly shown in Figures 3' and 9, the meeting rails 49 and 4| of the upper and lower, sashes are provided with overhanging ledges 42 and 43, respectively, and these ledges are each provided with a depending flange 44 and 45. Within the overhanging ledge 43 and mounted therein by means of an upwardly inclined pro- .iection 46, is a resilient substantially V-shaped Weatherstrip 41. When the meeting rails are not in contact, one side of the Weatherstrip 4'I has its resilient free end 49 engaging against the depending flange 44, but when the sashes are moved to closed position, the ledge 42 engages against the Weatherstrip and forces it inwardly as shown more clearly in Figure 3, to thereby; provide a weather-tight seal for the length of the meeting rails.

Figures and 6 show a plate retainer 48 for the weathering l2 in the side rails. This retainer comprises a preferably metal plate 49 having tongue'50 substantially conforming to the width of the. upper and lower sash rails 23, 40,

4| and 21 of the upper and lower sashes 3 and 4,

3 and 4 and the parting strip I0 is closed by a rubbing block or plate 55. This plate is prefering projecting beyond the sides or edges thereof forming a continuous sealing contact for the full length of the sash rail 23 and at both the interior into contact with the sash rails.

Figure 11 discloses an alternate/construction of weathering 51 having ribs 58, 58 for anchoring or attaching it to the projecting sides I! of the side rails ii. This is of resilient metal with its opposite sides 59, 59 corrugated vertically for spaced line contact with the interior surfaces of the sash runs 8 and 9 in the side jambs.

In Figure 12 is disclosed a further alternate construction of weathering in which the resilient Weatherstrip I2 is similar to that disclosed in Figure 4 but in which a pile cloth 60 is rolled into and anchored in the metal weathering in a manner similar to that of the cloth M. In place of the cloth, an extruded plastic may be substituted.

Where adjoining side jambs are "to be connected, the novel invention comprehends the use of substantially U-shaped mullion clips 6|. Each clip has its opposite sides provided with outwardly and oppositely projecting flanges 62 punched or otherwise formed from the opposite When the sides of the clip aresides thereof. projected through spaced openings in the adjoining side jambs 5, 5, the flanges 62 will lock against the rear surface of the jambs and anchor these parts together. Any desired number of these clips may be provided in vertically spaced relation to provide a rigid connection. A suitable snap-0n trim 63 formed of any resilient metal suitable for the purpose, may be provided.

From the above description and the disclosure in the drawings, it will be apparent that the novel construction comprehends novel dovetailed sash-runs which are wider at the'backthan at the front and rounded-at the back edge. These novel sash runs in combination with the novel weathering, will substantially and automatically eliminate sidewise motion of thesash as it Operates vertically within the side jambs while the rounded edge at the back of the sash runs will sashes, provides a most eifective seal thereat.

the side lambs, but allows suflicient space therebetween for the edge of a sheet or strip of felt or the like 53 to project therebeyond and into wiping contact with the interior surface of the jamb run. This sheet or strip'53 is carried by the plate 49. and anchored between this plate and a stiffener plate 54. The opening between the sashes The horizontal weathering for the top and bottom rails is so disposed and related that eflective sealing is accomplished even though the sashes are not completely closed. For example,- the weathering 30 in the bottom rail of the lower sash is so constructed that as this sash is lowered into closed position, the end 38 of the weathering will come into sliding contact with the sill 35 first and be forced out of contact and closure with the end 39 when it comes into compression contact with the sill. This provides dual weathering seals between the bottom sash and sill, in addition to the metal-to-metal contact betweenthe spaced projections 28 and 29 and the sill 35. One purpose of this construction is to compensate for possible irregularities in buildin constructions in which the windows are used.

Another feature of the weathering 30 is that it is so designed asto provide a strong tension against the base of the bottom rail 21 and against which the upper surface of the weathering. rests to insure permanent and positive engagement between the lower edge of the sash and the lower corner of the weathering.

The horizontal weathering for the meeting rails in addition to that provided by the overlapping flanges or projections on these rails, comprises a metal weathering carried in one of the sash rails which is substantially V-shaped and 'in spring or resilient contact with the projection on the other sash rail, whereby when the window is closed and these sash rails are in contact or substantial contact. the resilient metal weatherin will prevent infiltration of air in either direction. The shape of this resilient Weatherstrip is such as to include an angular portion at itsupper edge which insures complete and positive retention of the weathering within the appointed space.

The head weathering 24 provides a double seal spring contact that closes tightly before the sash is completely closed. This weathering being anchored byscrews or other attaching means within the dovetail sash-run, has its opposite sides so contoured and arranged as to normally project inwardly and away from the sides of the sash-run. until the sash is sufficiently raised as to engage the ends 25 and 26 and force these ends outwardly and the integral sides of this weathering back into the recesses provided therefor.

It is to be understood thatthe sashes will be counter-balanced by suitable means to facilitate vertical operation.

mechanism, and glazing will be accomplished and the window frame sealed in place in the wall by caulking in any conventional manner.

It will also be apparent that the invention comprehends the manufacture of single windows that can be assembled into groups of two or more without change in their construction. All that is necessary is to punch or provide openings in the adjoining side jambs or frame members 5 and these jambs when butted together and strengthened by the channel members 6 which are preferably spot welded thereto, are locked in that position by mullion clips having their opposite ends projected through these openings. These mullion clips may be spaced apart vertically a suitable distance, for example, twelve to twentyfour inches, 'and when the resilient flanges or retainers which are shown as punched out of the side walls, are forced through the openings in the jambs, lock the frames together. These mul- Also these sashes will be 1 locked in closed position by suitable locking for provided with side jambs, vertical sash-runs in the side jambs, a sash slidable in the sashruns and concealed weathering movable with the sash and comprising anoutwardly opening, sub-- dow frame, comprising a substantially U-shaped \resilient metal Weatherstrip having its base anchored onto and carried by the sides of the sash and a fabric strip impregnated with lubricant and secured upon each of the opposite resilient projections of said Weatherstrip for maintaining the fabric in wiping and sealing contact with adjacent surfaces of the window frame.
